Github user aljoscha commented on the pull request: https://github.com/apache/flink/pull/1513#issuecomment-184196790 I rebased on top of current master. Btw, still still has the issue that the time characteristic only applies to window operations that are created after setting the time characteristic. Changing the time characteristic does not affect already created window operations. --- If your project is set up for it, you can reply to this email and have your reply appear on GitHub as well.

Github user StephanEwen commented on the pull request: https://github.com/apache/flink/pull/1513#issuecomment-181776065 For new classes, it makes sense. Was a mistake on my end to name them like this in the first place.

Github user StephanEwen commented on the pull request: https://github.com/apache/flink/pull/1513#issuecomment-181511999 Is the switch from `ProcessingTime` to `PROCESSING_TIME` actually necessary? Breaks yet one more thing for users just because of a matter of taste. There are only so many breaking changes that we can do without upsetting people too much, and I would like to make those where it makes a difference. --- If your project is set up for it, you can reply to this email and have your reply appear on GitHub as well.

GitHub user aljoscha opened a pull request: https://github.com/apache/flink/pull/1513 [FLINK-3243] Fix Interplay of TimeCharacteristic and Time Windows This adds dedicated WindowAssigners for processing time and event time. timeWindow() and timeWindowAll() respect the TimeCharacteristic set on the StreamExecutionEnvironment. This will make the easy stuff easy, i.e. using time windows and quickly switching the time characteristic. Users will then have the flexibility to mix different kinds of window assigners in their job. This also expands the translation tests to verify that the correct window operators are instantiated.
